Head gasket for magnum block and la head
It should be fine. We've used Felpro 8553 Perma Torque LA head gaskets on magnum engines without any issues.
This is just for an example, but the only problems I have see have been magnum gaskets on an LA. This is a Felpro 540SD magnum head gasket and the pushrod holes in the gasket do not line up with the pushrod holes (about half off to the inside) in iron 360 heads but are very close to aligning with the pushrod holes in a 318 LA head. An arbor press type sheet metal pin punch could enlarge the holes without issues. But if you notice, it has the oil holes for LA rocker shaft oiling. But in your case, you should be okay with LA head gaskets whether oiling through the head or through the pushrods as long as you get the bore size reasonably close.
